- The 30KV (SF6) gas Insulated ring main unit has the advantages of compact structure, fully enclosed, fully insulated layer, long service life, maintenance free, small indoor space occupation, reliability, and no harm to the working environment. It is widely used in industrial production and civil cable ring networks and power supply system tails. Very suitable for small and medium-sized secondary substations, switching stations, factories and mining enterprises, airports, railway lines, residential communities, multi-story buildings, highways, subway stations, tunnel construction and other industries.
- Standards: IEC60265, IEC60298, IEC60420, IEC60694, IEC60056, DIN47636 National industry standards: GB/T11022-1999, GB3906-2006, GB3804-2004, GB16926-2009. GB/T11023-1999, GB1984-2003, GB1985-2004, DL/T404-2007
Product advantage
- The 30KV (SF6) gas Insulated ring main unit dust collector uses high-quality 2mm thick stainless steel plate casing.
- The stainless steel plate is cut and formed by fiber laser cutting, and welded by excellent welding robots worldwide, ensuring the sealing of the dust collector.
- Fill the gas box with SF6 vapor and undergo synchronous vacuum packaging for leak detection; The high-voltage load switch, grounding device power switch, circuit breaker insulation layer cylinder and other power switch themed movable components, as well as the bus duct, are sealed in a stainless steel plate air box. The waterproof level of the air hood is P67, and the dust collector is equipped with a glass diaphragm. When the internal pressure of the power switch exceeds a certain working pressure, it can be discharged from the explosion-proof port below, which can reasonably avoid harm to people, cables, and other switchgear in the distribution station.
